A middle oligocene pollen and spore assemblage from the bristol channel

FossilCathaya(Pinaceae) Pollen from the Canadian High Arctic

“…In addition to the above binomials, the name "Pinus Haploxylon-type" has long been used for Cathaya-like fossil pollen (e.g., Doktorowicz-Hrebnicka 1960;Oszast 1960;Lona and Ricciardi 1961;Gray 1964;Hopkins 1969;Boulter and Craig 1979;Nghia 1974;Herter 1985). Rudolph (1935, pp.…”

A critical review of the glaciomarine model for Irish sea deglaciation: evidence from southern Britain, the Celtic shelf and adjacent continental slope

“…The clays contain rare striated and faceted clasts of local derivation and abundant reworked palynomorphs of Tertiary age, suggesting derivation by grounded ice from the highly organic mid-Oligocene sequence infilling the Stanley Bank Basin (Fig. 6), which lies immediately to the northwest of the Taw/Torridge estuary (Boulter and Craig, 1979;Tappin et al, 1994). The glaciolacustrine clays were overridden by grounded ice following deposition.…”

Stratigraphy and palaeoenvironment of the Lower-“middle” Oligocene units in the northern part of the Western Taurides (İncesu area, Isparta, Turkey)

“…The species has been identified in the ''middle" Oligocene of Belgium (Roche, 1988) and the Netherlands (Schalke, 1988). In England, it has been found in ''middle" Oligocene strata of the Bristol Channel (Boulter and Craig, 1979). But, the species was not recorded in the Upper Oligocene deposits of the Thrace Basin and the southwest Anatolian molasse basins (Kale-Tavas and Denizli) (Nakoman, 1968;Akgün and Sözbilir, 2001), whereas it was reported from the Lower Oligocene Osmanoglu Formation of the Çankırı-Çorum Basin (Central Turkey) by Akgün (2002).…”

“…It has also been recovered from the Upper Oligocene and Lower Miocene sediments of the southwest Anatolian molasse basins (Kale-Tavas and Denizli) (Akgün and Sözbilir, 2001); and the Lower Oligocene Tokça Formation of the Çardak-Tokça Basin (Akkiraz and Akgün, 2005). Although the genus Dicolpopollis is not restricted to the Oligocene, it is regularly found in the Oligocene deposits of Northwest Europe (Boulter and Craig, 1979;Wilkonson et al, 1980), and the Oligocene sediments of North India (Salujha et al, 1974). C. simplex (Potonié and Venitz, 1934) Thomson and Pflug, 1953 has been reported by Nakoman (1968) from the Lower Oligocene of the Agaçlı ( _ Istanbul) lignites.…”
